Crayon holder and protector



Nov. 1, 1938. M. c. DvoRAK I CRYON HOLDER AND PROTECTOR 'Filed June 13, 1938 Patented Nov. 1, 1938 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to a protector, gripping and holding device for crayons or pencils of various kinds, particularly pencils and crayon of the type used for marking articles in manufacturing processes and other industrial uses.

In certain manufacturing and production processes such as, for example, the pre-treatment of metal plates prior to enameling, or where any metal or other bulky material must be subjected to successive baths previous to application of enamel or other surface coatings thereon, it is customary that each individual steel or other metal part be marked with its appropriate nurnber to identify it, either as to part number, job number, process, or the like. Itis customary to use a colored crayon to apply such identification or mark to the part prior to the beginning of the initial step of a series of steps to which such part is subjected in the production line. It has been found that as the part is repeatedly handled or immersed in various baths the identifying mark is obliterated'or rubbed off, with the result that the identifying mark must be repeatedly applied to the part by a number of persons who handle it successively; all this resulting in the necessity of having nearly every person handling the part to have a crayon always at hand. Great difficulty is experienced, especially by those persons who handle processes or steps involving application of liquid, senil-liquid or paint like materials, in gripping and holding crayon and in maintaining such crayon conveniently at hand for instantaneous use.

More particularly the invention consists of an elongated passaged handle-like gripping element formed of suitable material, preferably rubber of substantially yieldable texture, and embodying structural elements providing adjustability of the device for various size crayons and pencils.

It is therefore an object of my invention to provide an elongated handle-like substantially cylindrical holding and protecting device for crayons or pencils, preferably formed of yieldable resilient material and adapted to receive the main portion of the crayon or pencil and to hold another portion thereof in projected position.

A further object of my invention is the provision of a. holding device for crayons or pencils or the Alike consisting principally of a hollow cylindrical handle-like unit having a longitudinal passage therethrough for the insertion and engagement of the main portion of a crayon or pencil, and including removable ring-like elements for fasteningcrayons or pencils of various'diameters in said unit.

A further object of my invention is the provis ion of a protecting and holding device for crayons or pencils and the like which is adapted to grip and hold crayons or pencils of various diameters, and permitting the crayon or pencil to be repeatedly projected outwardly as it is used up whereby substantially all of the crayon or pencil will be used up, and at the same time providing a convenient gripping and holding means regardless of the length of the crayon or pencil.

A further objectl is the provision of a crayon protecting and holding device for various sizes of crayons or pencils which is longitudinally passaged and has elastic elements for frictionally mounting the`crayon or pencil therein, and which has one or more external flat surfaces to prevent rolling of a unit when it is laid down from time to time.

Other and further important objects of my invention will be apparent from the description in the specification and in the accompanying drawing.

This invention (in a preferred form) is illustrated in the drawing and hereinafter more fully described.

On the drawing:

Fig. 1 is a side elevational view of my crayon holder and protector.

Fig. 2 is an enlarged cross sectional view through the center therein.l

Fig. 3 is a cross sectional view taken on line 3 3 of Fig. 1.

Reference numeral Ill designates a cylindrical or tubular bodypreferably made of rubber or compositionthereof with other materials to impart yieldability, resiliency and flexibility. Said hollow body l0 is preferably formed'with enlarged end portions of bulb-like shape designated by lila and Illb respectively'. Numeral Il e designates a central longitudinal passageway of relatively large size which is defined by an annular cylindrical wall, and the same is preferably formed in the molding of the body in a. single complete unit. Passageway Il extends throughout the length of the body as clearly shown in Fig. 2, and at both the opposite ends is enlarged adjacent the ends of the body to form enlarged annular portions I2 or said passage at opposite ends respectively. Said enlarged portions are substantially the shape of an annular groove, and their formation forms annular shoulders I3 at opposite ends respectively'of the passage Il.

The opposite extreme ends of the body have formed integrally therewith annular flanges I4 which preferably project inwardly and into the passageway, and the flanged ends of the body at said opposite ends are preferably substantially thin so that said anges are elastic and stretchable to permit insertion and mounting of annular ring elements or ring members I5 which are preferably of a size to ilt snugly within the enlarged end portions I2 'of the passage il and which preferably seat against the shoulders I3. as indicated in cross section in the upper portion of Fig. 2.

The flanges Il are so formed that they project inwardly to either removably hold an annular gripping ring or member I5 or to frictionally engage and grip the external surfaces of a pencil, crayon or the like.

It will be apparent that when the larger sizes of crayon or pencil are inserted in the holder, that is, those of a diameter which will substantially fill the passageway I I, the flexible anges Il `:vill first be stretched outwardly to enlarge the diameter of the openings which either or both thereof define openings to permit insertion of a crayon, pencil or the like, whereupon the natural tendency of the rubber will grip and hold the pencil in the desired position with respect to the body I0.

In many and various industrial processes, crayons, pencils and marking devices of different sizes and diameters are employed, and for this reason my invention includes means providing for gripping, holding and protecting of crayons or pencils of various sizes. When pencils or crayons of the range of smaller diameters are to be mounted, any one of a number of sizes of removable rings I5, preferably made of rubber or rubber composition, may be inserted in one or both of the enlarged portions I2 of the longitudinal passage II, the outside diameter thereof preferably being slightly greater than the diameter of the opening deilned by flanges I4, In the insertion of such disks, ring elements i or members, the flanges I4 are flexed or stretched outwardly on diametrically opposite sides and the ring members Il are easily inserted into position against the angular shoulders I3. The internal aperture I5a of the ring members or ring elements I5 are of a range of sizes so as to cause a snug flt for an inserted crayon or pencil, that is, So that the fit will be such that a suflicient friction results to grip the crayon or pencil and hold it during normal writing operation, but which will also be such as to permit manual insertion or selective successive projection of the crayon or pencil end of the latter when it is used up in the writing process.

From reference Figs. 1 and 3, it will be noted that the external surfaces of each of the bulbshaped portions Illa is flat at opposite sides. This may aim to prevent undesirable rolling away of the crayon holder and protector when it is laid down upon any convenient supporting surface during the work operations.

Various changes may be made in the embodiment of the invention herein specifically described without departing from or sacrificing any of the advantages of the invention or any features thereof, and nothing herein shall be construed as limitations upon the invention, its concept or structural embodiment as to the whole or any part thereof except as defined in the appended claims.

I claim:
